Tyrosine-sulfated peptide hormone induces flavonol biosynthesis to control elongation and differentiation in Arabidopsis primary root.

This study shows that the peptide hormone PSY1 promotes root growth by inducing flavonol biosynthesis, which regulates cell elongation and differentiation in Arabidopsis.

A chimera including a GROWTH-REGULATING FACTOR (GRF) and its cofactor GRF-INTERACTING FACTOR (GIF) increases transgenic plant regeneration efficiency

The paper shows that a chimeric GRF4-GIF1 protein enhances transgenic plant regeneration efficiency in wheat, triticale, rice, and citrus, enabling marker-free selection and CRISPR-Cas9-based genome editing.

Variation and inheritance of the Xanthomonas gene cluster required for activation of XA21-mediated immunity

The paper identifies the raxX-raxSTAB gene cluster in Xanthomonas species and shows its role in RaxX peptide production, which is required for XA21-mediated immunity but not for peptide hormone activity.

The Rice XA21 Ectodomain Fused to the Arabidopsis EFR Cytoplasmic Domain Confers Resistance to Xanthomonas oryzae pv. oryzae

The paper shows that expressing a chimeric receptor with XA21 ectodomain and EFR endodomain in rice confers resistance to Xoo, indicating the ectodomain is key for robust resistance.
